  1. Where are you with this one?
    Convert mass CO2 to mass C.
    Convert mass H2O to mass H(atoms).
    1.0g - mass C - mass H = mass O

    Convert g C to mols.
    Convert g H to mols
    Convert g O to mols.

    Find the ratio for the empirical formula.
    Then (emprical formula) x number = molar mass. Solve for number (rounded to whole number).
    Then (empirical formula)n = molecular formula.
